Please Session Manager!!! come back!!! my life is not the same without you!!!

Actually, I downgraded to Firefox 56 just for this add-on.

If you want this add-on to come back just as I do, then ,please, send a feedback to the firefox team to do something about it. Just press "Alt", then Help>submitFeedback... and write about your love for this add-on and don't forget to add the next link at the end of the message.

If we all do this they will take it seriously and they will put it back to operation.
Please help with your Feedback!
